3,5,7,9,2,X
What number is X ????? > explain n get 100frih bucks...
Notice: The serie goes on infinitely and the numbers can be negative and will go negative at a point.
Bonus: When does it go negative? Point out the first number in the serie n get another 50 frihbucks!
Ok, any nutty mathfreaks out there??? )
It is a cheapskate nut to crack so come on!
X = 4.
the pattern would be 3,5,7,9,2,4,6,8,3,5 and so on.
Correct? Probably not but hey it was worth a shot!
That was really close!!!!
Sorry X is not 4.
U got 10 frih for trying
Oh well, at least a tried!
Thanks for the 10frih$ even though I was incorrect.

I've 'cracked' some very difficult examples of these in my day, and this one is not easy.
3,5,7,9,2,3,4,5,1,1,1,1,0,1,1,1,2,3,4,5,3,5,7,9,4,7,10,13
Well, that's my theory, and whether it is the 'correct' one or not, it does work.
Each number is the previous number + (x1), x is every 4th number, and x steadily decrements, regardless of previous number.
Gr8  correct!
It was easy  I told U!
U got frih comming.
^It wasn't easy!
It took me nearly an hour, spread over two days, to figure it out!
^.^
I really didn't think I had the right one though... I figured it was too complicated to be the real pattern.
Well my associate at work took 2 minutes to figure it out... But he does series all the time.

have U tried this one????? My workmate didn't even come close!
^I think there's not really enough there to give enough information though. The only way I can know that x decrements by one, instead of, say, being multiplied by 2/3 is because you said it would go negative.
I told the negative trend by a reason!
